The lifetime prevalence of epilepsy ranges from 2.7 to 12.4 per 1000 in Western countries. Around 30% of patients with epilepsy remain refractory to antiepileptic drugs and continue to have…
In this article, some specificities of functional magnetic resonance imaging (fMRI) in children (eg, blood-oxygen-level-dependent response and brain maturation, paradigm design, technical issues, feasibility, data analysis) are reviewed, the main…
Clinical application of functional magnetic resonance imaging (fMRI) based on blood oxygenation level–dependent (BOLD) effect has increased over the past decade because of its ability to map regional blood flow…
Resting-state functional MR imaging (rsfMR imaging) measures spontaneous fluctuations in the blood oxygen level–dependent (BOLD) signal and can be used to elucidate the brain’s functional organization. It is used to…
In this article, the basics of diffusion-weighted imaging/diffusion tensor imaging (DTI) are discussed, including a short historical perspective on the fiber dissection technique, followed by a review of selected brain…
Functional magnetic resonance imaging (fMRI) has become a common tool for presurgical sensorimotor mapping, and is a significant preoperative asset for tumors located adjacent to the central sulcus. fMRI has…
Preoperative mapping has revolutionized neurosurgical care for brain tumor patients. Maximizing resections has improved diagnosis, optimized treatment algorithms, and decreased potentially devastating postoperative deficits. Although mapping has multiple steps and…
Functional magnetic resonance imaging (fMRI) is used clinically to map the visual cortex before brain surgery or other invasive treatments to achieve an optimal balance between therapeutic effect and the…
This issue of Neuroimaging Clinics addresses the current clinical state-of-the-art in functional brain magnetic resonance imaging. Although other “functional” imaging modalities such as MR spectroscopy and MR perfusion imaging have…
